Yes. (Photo by James Gathany, Public Health Image Library (PHIL), Centers for Disease Control and Prevention) But it could be worse. Most blood-sucking insects urinate while they feed so they can avoid filling up on fluid and get more nutrients out of their meal But some species of mosquito also do what is called preurination — they excrete drops ...

According to Periodical cicada nymphs impose periodical oak tree wood accumulation Nature volume 287, pages 326–327 (1980): Densities of cicadas underground are very great — Dybas and Davis report emergence densities of over 300 nymphs per square yard or about 1,500,000 per acre. Where "Dybas and Davis" is A Population Census of Seventeen‐Year ...

Leaving aside the fact that termite CO2 production is on few, if any, secondary school syllabuses, its more complicated than that. Termites are not burning fossil fuels. The carbon they produce comes from decomposing wood. This carbon came from the atmosphere, and as the wood rots this carbon will wind up back in the atmosphere whether termites eat it or ...

"...the ground would practically be covered with them". Yes, this will happen. This cicada segment from the April 27th PBS News Hour at minute 3:42 shows the ground covered with cicadas (from the last time?) Then the property owner says there were so many moving around on the ground that he got sea-sick. Earlier it has a nice map of the Eastern US ...

There is no suggestion from the original photographers that spiders place water droplets on their heads. Web pages that re-post these photos don't have any references to support the notion. There are at least two photographers who stage these photographs. Consider Dmitriy Yoav Reinshtein whose gallery includes mantis with water droplet "hat" housefly ...

As people have commented, NASA isn't particularly associated with entomologists, so that seems to be a bit of a red herring and unnecessary appeal to authority. So what if NASA is confused by these bugs? Would it matter if your local mechanic was confused by these bugs? Or a Brain Surgeon? As was also commented, these species have been identified as Homaemus ...

Yes, maggots can infest the digestive tract of humans. I was able to find a number of articles describing this condition: Gastrointestinal Myiasis by Larvae of Sarcophaga sp. and Oestrus sp. in Egypt: Report of Cases, and Endoscopical and Morphological Studies - Korean Journal of Parasitology Four cases of gastric or intestinal myiasis are reported. The ...

Q Does switching the lights off help avoiding mosquitoes? In short: "yes", but with so much caveats that ultimately the needed qualifier is "but it's not effective". The caveats are: not all species at all stages of life-cycle. Even within the same species some inconsistent behaviours regarding light seeking or avoidance have been described. Some are ...

This is in wooded areas. When they emerge from the ground, they don't stay there. They go up in the trees and make their loud buzzing noises. Here is a picture from the web... SOURCE

As of roughly August 2021, per a note on Lemmino's video investigating the origins of Lisa Holst, Snopes founder David Mikkelson has admitted to fabricating the PC Professional article and the writer. Avery's anagram was correct.

No, an earlier list was published by Margot Anne-Stephanie Vigeant as author of the article Things to Stress Over in Cornell Engineer April 1992, volume 56, number 2, pages 24 and 25, (alternative link to full text): My first topic for this issue is worries. I've decided that there are just too many well adjusted, un-paranoid people in this school (NOT), ...

There is at least one citation reporting death in PubMed.1 I was not able to load the article, but having gone trough related literature on tarantula bites, it seems that a bite often causes localized necrotic ulcers,2 which, although not usually lethal, could lead to infection, gangrene, and death if left untreated. Some quick digging through newspaper ...

Probably not. There doesn't appear to be any evidence of the exploding stomach phenomenon. And most evidence to be found points in the opposite direction. Seeds are a natural food source. This is a study of the diet of one type of Ant in Oklahoma. And seeds are listed as an important dietary item. http://handle.nal.usda.gov/10113/11737 At grassland and ...

An article recently published by the BBC debunks this myth: http://www.bbc.co.uk/news/magazine-29281253 This claim was originally made by Harvard University professor Edward O Wilson, and the German biologist Bert Hoelldobler, in their 1994 book Journey To The Ants. They based their estimate on an earlier one by British entomologist C B Williams, who once ...

Nope. If insects ran rampant and ate everything, we could just eat them. Could Less Meat Mean More Food? “Nutritionally, it is excellent food,” says Arnold van Huis, an entomologist at Wageningen University in the Netherlands. “It’s the same or even better than conventional meat, fish, or poultry.” Just 100 grams of caterpillars can provide all of an adult’...

It's hard to find reputable sources on this issue, but let me present the two different takes on it that I found. According to this article: Cockroaches, apparently, have bulky bodies (composing of 3 heavy body segments) which are only supported by 6 long thin legs, As they die, they lose muscle-control causing the leg muscles to contract. As a ...

This link has reviewed several papers related to this technique , while they seem to agree that these traps do attract the mosquitos , but question the effectiveness in terms of the key outcome i.e reduction in mosquito biting rates, apparently what little evidnece exists points that there is no reduction in mosquito bites: Results of studies that are ...

Youtuber Lemmino actually located the only possible magazine that matched the description and got a copy of the article sent to him and translated.

It seems that Fabre's original claim has been greatly exaggerated by subsequent writers, and that the wasps are not nearly as stereotyped as those subsequent authors have claimed; Fabre's own description noted that not all wasps of the species showed this rigid behavior, and later studies have not supported it. The Sphex story is an anecdote about a ...

It looks like there is some basis to this: Attractiveness of Certain Popular Food Products to the German Cockroach, Blattella germanica, Adults under Field Conditions: Oily Products: The data summarized in Table (5) indicated that peanut butter was the most accepted product for both sexes and significantly attracted more insects (12.0 and 9.5 ...

Two points: The publication of The Pedant's Revolt by Andrea Barham took place after the original Snopes article, not before. The first edition of the book was in 2005. The Snopes article first appeared before then--I haven't found the original article, but there are forum comments from 2002 and 2004 which refer to it. So it was the book that referenced ...

It appears to have been discovered by a team including members from the sugar industry. They were looking for ways to use sucrose as a chemical intermediate. Most synthetic processes involve multiple steps. I have not found what (if any) final product was in mind. I can find no evidence that any of the participants were engaged in insecticide research. I ...

I think the answer is really in the physics of the cockroach, or other insect bodies. When the insect dies, rigor mortis sets in. Since the flexor muscles are almost always larger than the extensor muscles, the contraction causes the legs to bend inwards into the crossed position. The bug pulled into a cylindrical shape by rigor is now unstable, and is ...

They definitely repel fungus gnats. Do they repel other bugs? I have no idea. Sarah Zielinski, in an article on the Smithsonian magazine website, provides a simple summary of the research.

In Neurobiology of Chemical Communication., Chapter 5 - Chemical Communication in the Honey Bee Society, Section 5.1.2.5 Defensive Behavior: Alarm Pheromones details how trigger pheromones are released with the extrusion of the stinger whether or not an actual stinging has taken place.

The Question consists of three parts 1: Decline of insect populations. Is there any substantial and robust decline of insects in a large enough space and timespan to consider it a general decline? The overall abundance of butterfly species in Great Britain has declined by approx 70% in 20 years. http://science.sciencemag.org/content/303/5665/1879/tab-...

Research by Zhang QH et.al. in 2013 shows that for a category of wasps called yellow jackets, essential oils such as clove and peppermint showed significant repellency. Of the 21 essential oils tested, 17 showed significant repellency on yellowjackets [mainly Vespula pensylvanica (Saussure)] and paper wasps [mainly Polistes dominulus (Christ)]: clove, ...

While partial fipronil resistance in feline fleas has been reported, this resistance does not appear to be widespread, according to this study which found fipronil to be effective against feline fleas (this study used dogs as subjects, though I don't think that should make much difference as feline fleas were one of the parasites that was investigated). ...
